    摘要： PROBLEM TO BE SOLVED: To provide an optical device which can reduce sticking of foreign matter to metal pads at the time of cleavage.SOLUTION: The optical device comprises 32 light-emitting parts formed on one substrate and 32 electrode pads electrically connected to p-side electrodes in the 32 light-emitting parts. An electrode pad 150 where a silicon sticking symptom is likely to occur in a cleavage process is set in such a way that the length of a side thereof which is close to a cleaved portion in a plan view is longer than a dimension d in a direction parallel to the cleaved portion. In this case, even when the thickness of a chip forming substrate is greater than that of a conventional one, adhesive strength of a protective sheet can be reduced and sticking of silicon to each electrode pad at the time of cleavage can therefore be prevented. As a result, a manufacturing yield can be improved.
